2019 Ford F-350 Super Duty Check Engine Light Codes

In Mesa, AZ, technicians at Larry H. Miller Ford Mesa regularly decode the most common check engine light codes on the 2019 Ford F-350 Super Duty. Typical codes include oxygen sensor faults (P0130–P0167), catalytic converter efficiency (P0420), misfire codes (P0300–P0312), and fuel trim or EVAP system alerts (P0171–P0455). Left unaddressed, oxygen sensor or catalytic converter issues reduce fuel economy and increase emissions — problems that can be costly down the road, often requiring exhaust or sensor replacement. Misfires can damage pistons and catalytic converters if ignored, multiplying repair costs. EVAP leaks often start with a simple seal or gas-cap replacement but can escalate if contaminants enter the fuel system. Our Mesa service team diagnoses codes quickly with OEM-grade equipment, providing transparent estimates and highlighting how immediate dealer-grade repairs result in savings by preventing compounding failures. We emphasize convenience: comfortable waiting areas, loaner options, and efficient workflow to minimize downtime. To protect factory warranty coverage and ensure correct parts, we recommend scheduling with our certified technicians — schedule service today and check current service specials to reduce costs.
